Unable to pull from git repository (Sourcetree for windows v3.4.9)

[deepakoshi]

Hi 

Suddenly from yesterday I have been unable to pull from sourcetree. Each time I try it asks for my credentials but ends in an error. Initially it just said logon failed. 

I refreshed the OAuth token, updated to the latest version of sourcetree (3.4.9) but still had the same issue. 

I then uninstalled and reinstalled sourcetree. Now when I try to pull I get the following error - 

Please do let me know how I can resolve this

Thanks
